Alright, sorry for the cross-post, not sure where to send this. I THINK I got
linux's mmap2 working, but for some reason, the program I'm testing with (the
linux version of winex, the one that runs all those neat windows directx 8
games ;-) ) still does this (from truss)
linux_mmap2(0x65430000,0x100000,0x0,0x22,0xffffffff,0x6) = 1698889728

exit(0x0) process exit, rval = 0
this is the end of the truss output, can anyone tell me if anything in this
truss output looks like it would cause the program to exit without doing
anything? (this is what happens, it doesn't do ANYTHING at all
